Is this trial a fit for you?

Likely a good fit

Ideal candidates are adolescents and adults diagnosed with primary sclerosing cholangitis confirmed by liver biopsy or imaging.

Probably not a fit

Patients currently receiving biologic therapies or with serious liver disease may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of hymecromone combined with standard care for treating adolescents and adults diagnosed with primary sclerosing cholangitis (PSC). The primary objective is to compare the efficacy of this combination therapy against standard care alone. Secondary objectives include assessing changes in alkaline phosphatase levels and various biomarkers related to PSC over a six-month treatment period. Participants will be monitored for improvements in liver function and disease markers.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for managing primary sclerosing cholangitis, potentially improving patient outcomes.

How similar studies have gone: While there is limited data on hymecromone for PSC, similar studies exploring novel treatments for liver diseases have shown promise, indicating potential for success.
